 Posting as one thread is discouraged because it confuses patchwork

+Can I reproduce the checks from patchwork on my local machine?
+--------------------------------------------------------------
+
+Checks in patchwork are mostly simple wrappers around existing kernel
+scripts, the sources are available at:

+https://github.com/kuba-moo/nipa/tree/master/tests
+
+Running all the builds and checks locally is a pain, can I post my patches and have the patchwork bot validate them?
+--------------------------------------------------------------------------------------------------------------------
+
+No, you must ensure that your patches are ready by testing them locally
+before posting to the mailing list. The patchwork build bot instance
+gets overloaded very easily and netdev@vger really doesn't need more
+traffic if we can help it.

 Any other tips to help ensure my net/net-next patch gets OK'd?
